International Journal of Exercise Science

International Journal of Exercise Science 5(3) : 205-213, 2012. The aims of this study were to cross-validate three clinical-grade measures of body composition, using an octopolar Bioelectrical Impedance (BIA), an ultrasound analyzer (US) and Air-Displacement Plethysmography (ADP) and second to compare the US scans of total abdominal, subcutaneous and visceral fat depths (mm) against the trunk percent fat (%BF) from the octopolar BIA. Twenty-six college-aged (22.9 ± 1.35 years) men (n = 18) and women (n = 8) volunteered to participate in this study. Body composition was assessed using BIA (total and by segments), ADP and US. In addition, total …

Effects Of Short Term Low Intensity Resistance Training With Blood Flow Restriction On Bone Markers And Muscle Cross-Sectional Area In Young Men, Sojung Kim, Vanessa D. Sherk, Michael G. Bemben, Debra A. Bemben

International Journal of Exercise Science

Int J Exerc Sci 5(2) : 136-147, 2012. This study compared the effects of short term resistance training with and without blood flow restriction (BFR) on bone turnover markers and muscle cross-sectional area (MCSA) in young men (18-35 yrs). Subjects were randomly assigned to a BFR (20% 1RM) resistance training group (BFRT, n=10), a high intensity (80% 1RM) resistance training group (RT, n=10), or a BFR only group (BFR, n=10). Both BFRT and RT trained 3 days per week (2 sets, 10 repetitions) for 3 weeks for leg press, knee extension, and knee flexion isotonic exercises. BFR underwent the BFR …

Preliminary Analysis Of The Feasibility And Effectiveness Of Whole Body Vibration As A Therapeutic Intervention In A Skilled Nursing Facility, Kai Williams, Chris Goldstraw, Sheila Kellagher, Steven Tham, William E. Amonette

International Journal of Exercise Science: Conference Proceedings

Skeletal muscle sarcopenia results in loss of strength, power and functional capabilities leading to decreased independence and an increased reliance on the healthcare system. Exercise is an effective countermeasure to age related loss of muscle, but may be difficult in elderly patients with complex functional limitations. Whole body vibration (WBV) is a novel tool used to stimulate the neuromuscular system; research indicates it may improve strength, power, and balance in many populations. Purpose: The purposes of this study were to determine if WBV training is feasible in a skilled nursing facility and if standard of care (SOC) with augmented WBV …

Timed Up-And-Go Scores Are Associated With Balance But Not Lower-Extremity Force Production In Elderly Skilled Nursing Facility Patients, Christopher Barnett, Kai Williams, Chris Goldstraw, Sheila Kellagher, Steven Tham, William E. Amonette

International Journal of Exercise Science: Conference Proceedings

Aging is associated with numerous deleterious muscular, skeletal, and neurologic adaptations that may result in functional performance decrements. These decrements are accelerated during periods of unplanned physical inactivity (e.g. hospitalization). Reductions in gait velocity are well documented in the elderly and may result from fear of falling, poor balance, or inability to accelerate because of reduced ground reaction force capabilities. Purpose: To determine if timed up-and-go scores were related to balance or lower extremity force production in skilled nursing facility patients. Methods: Data were collected on 40 patients (77.1±1.4y; 164.2±1.7cm; 75.3±3.3 kg) in an inpatient skilled nursing facility. The 15 …

Pilot Study For Using Ecg In Pre-Participation Physical Exams In Collegiate Athletes, Bryan Ruiz, Matthew Massingill, Michael Cedeno, Jamie Cvikel, Steve Simpson, Joe Priest, Jennifer Blevins-Mcnaughton

International Journal of Exercise Science: Conference Proceedings

Title[j1] : Pilot Study for Using ECG in Pre-participation Physical Exams in Collegiate Athletes

Authors: Bryan Ruiz, Mathew Massingill, Mike Cedeno, Steve Simpson, Joe Priest, Jennifer Blevins-McNaughton (Clinical Exercise Research Facility, Tarleton State University, masters)

Background and Purpose: Disagreement exists in the sports medicine field concerning the best way to recognize and prevent unexpected deaths in sports. The purpose of this pilot study was to determine the extent to which using 12-lead ECG in pre-participation physical exams (PPE) meet diagnostic criteria for sudden cardiac death.

Methods: Twenty-seven (N = 27) Division II athletes ages …

Background and Purpose: Disagreement exists in the sports medicine field concerning the best way to recognize and prevent unexpected deaths in sports. The purpose of this pilot study was to determine the extent to which suspect cardiac conditions were present during pre-participation physical exams (PPE) in collegiate athletes.

West Texas A&M University, Canyon, TX¹ California Baptist University, Riverside, CA²

Irritable bowel syndrome(IBS) is common among female endurance athletes. This disorder, characterized by recurrent abdominal pain, inflammation, and disturbed bowel function, can also contribute to severe anxiety, depression, and fatigue. Quercetin has been used to combat pain, inflammation and fatigue in healthy athletic populations, but its efficacy in female endurance athletes with IBS is unknown. PURPOSE: To determine whether …

Increasing Strength And Muscle Mass In Hiv+ Men Recovering From Substance Abuse, Carianne M. Cregar, Jakob L. Vingren, John H. Curtis, Kiannah Williams, Julius F. Cantu, David W. Hill

International Journal of Exercise Science: Conference Proceedings

The combination of substance (drug and/or alcohol) abuse and infection with human immunodeficiency virus (HIV) can result in the development of several co-morbidities, including muscle wasting. Resistance training could, therefore, be an important tool in the treatment of substance addiction/abuse and HIV. PURPOSE: The purpose of this study was to examine the effect of resistance training on measures of muscle mass and strength in the context of co-occurring substance abuse and HIV. METHODS: Seventeen untrained men (Mean ± SD: 42 ± 11 years, 89.7 ± 16.0 kg, 179.7 ± 9.1 cm, 18.9 ± 5.5 %fat) who are infected with …

During exhaustive severe intensity exercise, the oxygen uptake (VO₂) increases exponentially, with a time constant of ~30 s. After ~1 to 2 min, a slow component emerges and drives the VO₂ to its maximum. There are clear differences in the VO₂ response profile across exercise intensity domains. These disparities might not …
